Catalog identifiers and variants
The descriptive filename Lexus LS460 1URFSE 89663-50360.bin associates this calibration with the LS 460 and its 1UR-FSE engine. The same identifier also appears as 89663-50360.bin and 89663-50360-B.
The -B suffix distinguishes a catalog label, but it does not identify a specific modification or feature. The filenames do not establish what changed in this calibration revision or whether the listed files have identical contents.
The LS 460 and engine designation provide useful context when identifying a record. They do not, on their own, establish compatibility with every LS 460 or 1UR-FSE application.
